Hi,
One other thing, which isn't really a major issue, just an annoyance,
is that if I run netstat or ps on the host it shows me all of the sockets
open and programs running, even those inside the guests, whereas under
linux-vserver the host machine is a context in it's own right, so they
are hidden.
I personally prefer that way, so I can easily see what's going
on in the VPS. But there should be some additional info from
which VPS the stuff is coming from. Maybe the VPS' process names
could contain some prefix ie. [${VPSID}].
You can use vzps/vztop utils from vzprocps
(http://download.openvz.org/contrib/utils/), whey show VEID.
OR, alternatively, you can look up VEID manually from the 'envId' field
of /proc/$PID/status file.

I just end up using the same process I use under linux-vserver to migrate guests between machines: rsync once, rsync a second time (to reduce the time stopped), stop the guest, resync a third time, start guest on new host. This is basically what vzmigrate script does (well, there's no intermediate rsync, but it can be added quite easily. I also have some other issues with openvz as well. One is related to the resource limits -- every guest I've built I've had to play with the limits to get the software I need to run. The defaults just don't seem usable. Perhaps those defaults are better suited for a lot of tiny/lightweight VEs. If your VEs are relatively large, I suggest you to either use vzsplit utility to generate an initial config, OR use something like example C from http://wiki.openvz.org/UBC_configuration_examples_table On the other side, the problem with linux-vserver is by default a guest (a VE) is NOT limited, which means you can not give it to an untrusted party without doing some additional work. The OpenVZ idea is like the one for your firewall -- deny all by default, then allow what you need. Here, as well, you start with a limited set of resources, and then tailor those to your environment. Of course it can be changed server-wide by having a different config set as default. One other thing, which isn't really a major issue, just an annoyance, is that if I run netstat or ps on the host it shows me all of the sockets open and programs running, even those inside the guests, whereas under linux-vserver the host machine is a context in it's own right, so they are hidden. There is a two-liner patch available to switch to hide VE processes from VE0 behavior: http://download.openvz.org/contrib/kernel-patches/diff-ve0-proc-own-processes-only My only issue with linux-vserver is the lack of network interface virtualisation, but I've been working around that for so long it's not really that much of an issue for me. My recommendation at this point is still towards linux-vserver. I'm planning on migrating work away from openvz back to linux-vserver as well. What are the reasons (if other than specified above)? ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
